Download Little Traverse Bay in Lake Depth Maps and its depth lines work with no signal: your position shows on the contours, with the depth under you read from the nearest lines. Pick two depths and the app lays a line of holes across the steepest break.

Water levels change. Not for navigation. A depth map says nothing about the ice. Check ice yourself, every trip.
